四位十进制频率计的源代码,详细,清楚地写出了设计语句(four decimal frequency of the source code, detailed and clearly written into the design statement)

永磁同步电机无传感器矢量控制方法研究及仿真(Research sensorless vector control methods and simulation of permanent magnet synchronous motors)

这是我本科的科研立项《基于热释电红外人数统计器》 里面是源码，keilC51。(This is my undergraduate research project based on pyroelectric infrared statistics on the number of " inside source, keilC51.)

stm32f4 + usb3300 高速 usb msc(stm32f4+ usb3300 speed usb msc)

STM32使用USB进行程序IAP升级的源程序，经过实际验证，非常好用(STM32 IAP upgrade using USB for program source code , very easy to use)

可以通过STM32的AD采集测出正弦波的频率，并在液晶屏上显示出来。（原子的mini板可直接用）(AD can gather through the STM32 measured sine wave frequency, and displayed on the LCD screen. (Atoms mini board can be directly used))

以监控和控制为目的的算法因为其数据要在数据中心汇总和处理，大多使用集中式算法，其精度较高，但通信量大。分布式算法是传感器节点在采集周围节点的信息后，在其自身的后台执行定位算法，该方法可以降低网络通信量，但目前节点的能量，计算能力及存储能力有限，复杂的算法难以在实际平台中实现(To monitor and control algorithms for the purpose because of its data to be aggregated and processed in the data center, mostly using centralized algorithm, its high accuracy, but the communication volume. Distributed algorithm is the information collected in the sensor nodes around node positioning algorithm executed in its own background, the method can reduce network traffic, the limited energy of the current node, computing power and storage capacity, the actual complex algorithms difficult platform to achieve)

说明：  oled-iic通信通用代码，只需改.h里的修改部分即可使用。(The general code of oled-iic communication can be used only by modifying the modified part in. H.)

在stm32的cpu上移植freertos操作系统，程序在freertos基础上实现了，按键扫描，led灯控制，串口收发处理，定时器中断程序等功能。使用MDK打开工程文件即可。(Stm32 on the cpu transplant freertos operating system, the program freertos based on realized, key scan, led lamp control, serial port transceiver processing, function timer interrupt procedures. MDK can open the project file.)
